good to know that. i thought

There's an app...

For almost anything you can think of - and probably some things you've never thought of...

The GPS apps on iPhone I've used thus far lack the ability to do custom POIs, and optimized routing - so if those things are deal-breakers for you, the stand-alone GPS that does what you want is still the way to go - but the apps are evolving, and getting better all the time.

What would be the perfect thing - in my opinion - would be a GPS app on a phone that would be a "data conduit" for a stand alone device - giving all the best of both worlds.

There is an Iphone app that does custom pois

http://www.alk.com/copilot/ -- uses OV2 for the poi file format - so a csv file from here could be converted to OV2 and used... However, it appears you'd need a means of dropping files into the iPhone's physical storage... to do that on a mac, I use iPhone Explorer. Similar programs for Windows exist.

Which one is more

Accuracy?

Which one is more accurate/reliable, PhantomAlert or POI file created on this website?

I'm not sure I know the answer to that. The POI file has something like 3,600 red light cameras and another 450 speed cameras. PhantomAlert lists something like 144,000 entries, but that includes speed & red light cameras, speed traps (useless to me, since they are moving target), school zones, and DUI checks (which I think is useless). I just download the database for speed & red light cameras from their site into my BlackBerry & Garmin, since that is all I'm interested in.

The major difference, though, is probably that the PhantomAlert database is updated & verified online by all users, whereas the POI file is more limited in updates.

What it all comes down to is probably a matter of preference. I like the BlackBerry option when I'm in a rented car or otherwise without my Garmin.
